The **ATG-2113-R** is a high-performance **Power Signal Generator** (often categorized as a power amplifier with an integrated signal source) manufactured by Aigtek. It is specifically designed to drive capacitive and inductive loads with high precision in laboratory and industrial R&D environments. --- ### ## Technical Specifications Below is a breakdown of the primary electronic characteristics of the ATG-2113-R: | Parameter | Specification | | :--- | :--- | | **Output Waveforms** | Sine, Square, Triangle, Pulse, Sawtooth, DC | | **Maximum Output Voltage** | 800Vp-p (±400V) | | **Maximum Output Power** | 120W | | **Frequency Range** | DC to 1MHz | | **Output Current** | 300mAp | | **Voltage Gain** | 0~100 (Adjustable) | | **Input Impedance** | 50Ω / 100kΩ (Switchable) | --- ### ### Key Electronic Components & Features #### 1. Dual-Channel Architecture The device typically operates with a high-voltage power amplification circuit. It can function as a standalone signal generator or as an external power amplifier to boost signals from an existing DAC or function generator. #### 2. High-Voltage Output Stage The core of the ATG-2113-R is its **Linear Power Amplification stage**. Unlike PWM-based amplifiers, the linear design ensures: * Low harmonic distortion. * High signal fidelity across the 1MHz bandwidth. * Stability when driving complex impedances (Piezoelectric ceramics). #### 3. Control Interface The system integrates a digital control logic board that manages: * **LCD Display:** For real-time monitoring of voltage and frequency. * **Protection Circuits:** Over-current and over-temperature sensors that shut down the output stage to prevent component failure. * **Numerical Control:** Digital encoders allow for precise gain and frequency stepping. --- ### ### Typical Application Circuit In a common laboratory setup, the ATG-2113-R acts as the power driver between a controller and a transducer. ```mermaid graph LR A[Signal Source/Internal MCU] --> B[Pre-Amplifier Stage] B --> C[Power Amplification Stage] C --> D[Output Filter/Protection] D --> E[Load: Piezo/Inductor/Plasma] ``` --- ### ### Usage Precautions 1. **Impedance Matching:** While the device is robust, ensure the load does not exceed the 300mA peak current limit at high voltages. 2. **Heat Dissipation:** The unit uses active cooling. Ensure the rear fans are not obstructed during high-power (120W) continuous operation. 3. **Grounding:** Ensure common ground between the input signal source and the ATG-2113-R to prevent ground loops.
